Application .filed February-.24, 1920..., Seria1 1 To..360,819.

T0 .aZlac/ zom it may concern:

Be it known that I, PETEIV Know, a citizenof the United Statesof Amerlca, re-

siding in the borough of Brooklyn, county of .Kings, and Stateof New York, have invented certain new and useful Improvements in Can-Body-Forming Machines, of whichthe following is a specification.

This invention relates to automatic-,machines for forming can bodies, and provides an automatic machine in which can bodies having diiferent shapedends, andusually tapered, maybe formed, and may be removed from the forming, born without mar-- ring, or with aminimum of marring. I

Thelmvention further provides anovel combination and arrangement of parts for accomplishing the results referred to, hereinaftermore fullyset forth, and pointed out in the .appendedclaims. v

An embodiment, of the invention, is illustrated in the accompanying drawings, In

said drawings Figure. 1 illustrates so much of an automatic .bodymaker, incorporating the present invention, as is necessary to illustrate...the invention, the. figureshowing-the parts in vertical section.

Fig. 2 is an end elevation of the; parts shown in Fig. 1. t

priorpatents, for example, 1,234,182, dated July 24th, 1917, 1,129,302,, dated February 23rd 1915., both granted to Peter-Kriji'se, ,1

The machineis herein shown as adapted to form a .can body which'is, oval at one end andslightly oblongat the other}- end, the two ,endsof the oanbeing of diffenent shapes. and thehorn 10 is correspondingly shaped; J.

that is it is substantially'oiva-l at one end and; substantially.oblongat the other end.

Moreoverthe can body is here shown as tapered, the, horn having. a corresponding taper. The can body, however, mayor may notbe ,taperedand the particular .shapes given are given merely by way of i1lustra,

tion of .can bodieshavingdiffer'e'ntshaped ends.

In operation, bodylblanks are. fed along,

the feed table120,,on to the, ledge 12 beneath, j

the. born 10, the blanks havingbeen pre-- .viously edged, (or. notched and edged) and when in position between the, ledge; 12 and born 10 they "are. wrapped aroundthe horn by the wingsd, the. hooked edges being,

overlapped, and the; horn expanding to bring the hooks on (the, overlapped edge'sto-1 gether. .Thereupon the bumper 1-6, ,which has been approaching, ,strikesthe can body edges, and closes .thesean -in a; well ,lmown along the seam, formed by the; inter-hooked. =5

manner. ,The expansion of the horn may, as heretofore explained, be efiected. by Qthejf expander slide 27 acted uponrby the "beam .17 carrying the bumper.

the body off the horn. The side of the horn adjacent to the ledge 12 is parallel to said ledge, in order that the blank may have a straight line feed, and if the formed blank were slid from the horn in the forming position, it will be seen (especially with reference to Figs. 6 and 7) that the rear end of the body would have its portion which is adjacent to the ledge, squeezed between the front end of the horn and the said ledge, thereby bending out of shape and marring the rear endof the body. In order to avoid this marring of the can body, the horn is lifted, or the horn and ledge are relatively moved, to an extent which will permit the shape or outline of the front end of the horn coinciding to the greatest possible degree with the shape or outline of the rear end of the can body to be ejected. Moreover the lift of the horn is preferably effected in timed relation to the advancing move ment of the feed bars and dogs 22, 23, so that the can body is not raised from the ledge 12, and slides along or close to said ledge, whereby the feed dog 23 remains against the rear end of said can body throughout its movement off of the horn. Fig. 6 shows the can body immediately after being formed, and shows the front end of the horn by cross-hatching. Fig. 7 shows the can body as it is leaving the horn, the outline of the front end of the horn being shown in a position coinciding with the outline of the rear end of the can body and being shown by cross hatching. From these figures and from the foregoing description it will be seen that the can body passes off the horn without being bent or dented. In all cases of can bodies with different shaped ends, the present invention permits of the can bodies passing off of the horn without being dented or with only minimum denting or marring. \Vhere it is possible to avoid denting, this can be effected by the present means.

The lifting of the horn may be effected in any suitable manner. As here shown the horn is fixed to the slide 40. This slide is moved up and down by means of a rock arm l-l, one end of which has a pin and slot con nection 42 with the slide, and the other end of which is connected to an actuating rod ll), having a finger or roller 4-4 driven by a suitable cam, as indicated at 4-5. 46 designates a crank-disk which may be used to reciprocate the feed bar 22 through a lever 4-7. and links 48, 4:9. The timed relation of the feeding mechanism and of the hornlifting mechanism may be seen from Fig. 9.

The inventive ideas herein set forth may receive other embodiments than that which isspecifically illustrated and described.

hat I claim is 1. A can body forming machine adapted to form bodies with difierent shaped ends,

comprising a correspondingly shaped horn, a closely adjacent ledge between which and the horn a body blank moves, feed means on said ledge for ejecting a body from said horn, and means acting in timed relation with said feed means for separating said horn and ledge to an extent permitting the rear end of a body formed on the horn to pass over the front end of a horn in a position wherein its outline coincides most nearly with the outline of the front end of said horn, said feeding means and said means for separating the horn and ledge acting simultaneously, whereby said body is not substantially lifted from said ledge during the ejection.

2. A can body forming machine adapted to form bodies with different shaped ends, comprising a correspondingly shaped horn, a closely adjacent ledge between which and the horn a body blank moves, feed means on said ledge for ejecting a body from said horn, and means acting in timed relation with said feed means for separating said horn and ledge to an extent permitting the rear end of a body formed on the horn to pass over the front end of a horn in a position wherein its outline coincides most nearly with the outline of the front end of said horn, said ledge being substantially parallel to the adjacent face of said horn, said feeding means and said means for separating the horn and ledge acting simul taneously, whereby said body is not substantially lifted from said ledge during the ejection.

3. A can body forming machine adapted to form bodies with different shaped ends, comprising a correspondingly shaped horn, a substantially level feed table along which blanks are fed, a closely adjacent ledge between which and the horn a body blank moves, said ledge being substantially parallel to the adjacent face of said horn and being in prolongation of said feed table, feed means on said ledge for ejecting a body from said horn, and means acting in timed relation with said feed means for separating said horn and ledge to an extent where the outline of the rear end of said horn most nearly coincides with the outline of the front end of said horn previous to the lifting of the horn, said feeding means and said means for separating the horn and ledge acting simultaneously, whereby said body is not substantially lifted from said ledge during the ejection.

4. A can body forming machine adapted to form tapered bodies with different shaped ends, comprising a correspondingly shaped horn. a substantially level feed table along which blanks are fed, a closely adjacent ledge between which and the horn a body blank moves, said ledge being substantially parallel t9 the adjacent face of said horn and being in prolongation of said feed table, feed means on said ledge for ejecting a body from said horn, and means acting in timed relation with said feed means for separating said horn and ledge to an extent where the outline of the rear end of said horn most nearly concides with the outline of the front end of said horn previous to the lifting of the horn, said feeding means and said means for separating the horn and ledge acting simultaneously, whereby said body is not substantially lifted from said ledge during the ejection.

5. A can body forming machine adapted to form bodies with different shaped ends, one end being substantially oval and the other end being substantially rectangular, comprising a correspondingly shaped horn, a closely adjacent ledge between which and the horn a body blank moves, feed means on said ledge for ejecting a body from said horn, and means acting in timed relation with said feed means for separating said horn and ledge to an extent permitting the rear end of a body formed on the horn to pass over the front end of a horn in a position wherein its outline coincides most nearly with the outline of the front end of said horn, said feeding means and said means for separating the horn and ledge acting simultaneously, whereby said body is not substantially lifted from said ledge during the ejection.
